Example Prompts

- "Look up IOTA group NA-005"
- "Search for islands named Shetland"
- "What IOTA groups are near Boise, Idaho?"
- "Show me all islands in EU-005"
- "What IOTA references map to DXCC 291?"

Data Source

Data comes from the official IOTA website JSON downloads:

- fulllist.json — complete group/subgroup/island hierarchy (~1.3 MB)
- dxcc_matches_one_iota.json — 1:1 DXCC-to-IOTA mapping (~3.5 KB)

Data is downloaded once and cached for 24 hours (IOTA refreshes daily at 00:00 UTC).

Development

```bash
git clone https://github.com/qso-graph/iota-mcp.git
